` Throughoutthe drawings' `like numerals of Vreference'refer:alava s-tolike parts.

In generalathefembolliinentfof my invention comprises means forcreatingan annular maonetic field, an annular: coil arranged wit iintheiinfluence of said field adapted to receive feeble current, and byreason of its polarization, due. to thepassage of such current, to beattracted into-or repelled from the field, and means supporting saidcoil for vibration in the general direction-of its axis, whereby theattraction or repulsion produces a movement of the coil which istransformed by suitable means into mechanical work.

It will be understood that by the terni annular, as herein used, I donot intend to limit myself to a circular ring shape of the coil member,as it will become apparent that such member might readily be made polygenal in shape, but for convenience of construction I have illustrateda` true ring forni or coil, and for convenience in description will usethe terni annular throughout the specification and claims. I preferablyestablish the annular electrical field by the provision of a pluralityof magnets, preferably permanent magnets of the horse-shoe type,arranged all with like poles upon the saine side, that is the inside oroutside, of the i field area, said magnets being preferably so disposedthat the fields between their poles jointly form a strong magnetic fieldof generali-y annular form.

In the specific construction shown, 10-10 indicate permanent magnets oftorse-shoe shape, arranged generally in relation to cach other to fornisegments of a circle, and having their like poles onlike sides ot' thecircle, the outwardly arranged polesl of the magnet being connected by acontinuous pole piece 11, and the inner poles of the magnet beingconnected by a concentric, continuous pole piece A12. Preferably' thepole pieces 11 and 12 are generally circular in shape so that there isleft between iheinan annularfield space, wherein the magnets create astrong magnetic field. To conveniently provide .supports for the magnetl arrange a bracket 13 .forked at the center ot the circle f'oriiied bythe magnets and having its three branches or legs provided with recessesto receive the studs 14 and 15 provided at suitable points upon theannular pole pieces 11 and 12.

.Within the annular magnet field I arrange a coil generally indicated as1G, consisting of a 'thin core 16 preferably` of diagrammatic materialand a continuous wire 16b wound thereon, having its terminals 16disposed for convenient connection with a suitable electric circuit. Thecoil is sup )orted for movement in a direction generally parallel withits axis in any convenient way, its normal position heilig such (hat it.falls within the influence of the magnet field heretofore described, sothat when polarized by the passage of an electric current it moves inrespense to the attracting or repclling influence of the permanentfield. l `or convenience of construction the bracket 13 may be providedwith an arin 13 overhanging the magnet structure, and provided withbearings 13D for a pulley structure comprising a shaft 17, and a pulley18. To the shaft. 17 is connect-cd a suspending cord 19, at its lowerend connected to a spindle 20, carrying a spider 2l attached to andsupporting the core of' the coil. To the pulley 1S is secured a cord 22bearing at its lower end :i counterbalance weight 23 sufficiently hea vyto iiplnoxiinately balance the weight of the coil. By the differentialpulley arrangement shown the weight Q3 may bc made relatively light.

The stem 20 may conveniently serve as the moving part of the apparatusfrom which ower is transmitted, and to this endfor illustration of theoperation of the device as a relay- I provide upon the spindle a collar24, arranged for coperation with contact devices 25 sup orted on abracket arm 13c and adapted or connection in a suitable electric clrcuitto be infiuenced by the action of the responsive device. As a substitutefor the coil suspending structure described, the coil may be suspendedfrom a spring 26, as shown 1n Fig. 3,l or other suitable supportsadapted to normallyl maintain the coll in proper position, but to enableit to be moved 1n a direction generally along the line of its axis, mayobviously be employed.

In some instances it may, be deemed desirable to have theelectro-responsive device responsive only to direct current, or currentimpulses of one direction, and to thisend I provide a dash pot operatixrin general to the-same effect as does the ash pot shown in my rior`patent-No. 810,311, of January 16th, f-1 06.515 i i v the-specificnconstruction shown, the stem 2O extends4 through a guide a rture 27 inthe supporting arm 13, and-is urther directed by a uide 28, supported bya' tube 29,

secured to t e structure 13 in any suitable manner. By the structure 29support may also be conveniently afforded, through the agency of 'aspider 30,-for the dash. ot casing 31 in which plays the dash pot punger 32 provided with the valve openings 33 and rigidly, secured to the:free extremity Vof the spindle 20. A valve 34 may be arranged tooverlap the apertures 33 so that the dash pot operates at its fullresistance to move in a direction to permit the circuit controllingdevice 25 to be functionally operated by the rela mechanism.

e I have herein described in some detaila specific embodiment of myinvention, I do not desire tobe understood as limiting myself thereto,as the specific disclosure is made simply for pur oses of-full andadeuate description, an it will be apparent to t ose skilled in the artthat numerous changes in the mechanical structure might be made Withoutdeparture from the spirit and scope of my invention.

Having thus described my invention, what I claim and desire to secure byLetters Patent, of the United States, is;

l. An electro-responsive device comprising a coil, adapted forconnection in an electric circuit, having an open center, meanssupporting said coil for axial movement, and magnets arranged each withone ole inside and the other pole outside of sai coil, two continuouspolepieces Vjoining the interior and exterior poles of said magnetsrespectively, and Working parts associated with the coil to derive theirworking power therefrom.

2. An electro-responsive device comprising a frame, a plurality ofpermanent horseshoe magnets supported in common b said frame, incircular arrangementwith like poles inward, continuous pole pieces, onejoiningl the inner poles and .anotherthe outer poles of said magnets,said pole ,pieces being se arated by a narrow annular space, an ann arcoil for connection in anelectric icircuit disposed in said space, asuspension sup rt for saidfcoil arran ed to permit its am movement, andwoiing arts operatively associated with the coi? for actuation by .itsmovements.

3. An electro-responsive device comprising a coil adapted for connectionin an electric circuit, having an open center;` means supporting saidcoil for axial movement, two continuous para-magnetic ole pieces oneinside of and the other outsi e of said coil and separated by a narrowspace wherein the coil may move axially, and a ermanent magnet structurejoining the said pole pieces disposed to impart one polarity to theinner pole piece and the opposite polarity to the outer pole piece, anworkin parts associated with the coil to derive t eir working power fromits axial movements.

In testimony. whereof I hereunto set my hand in the presence of twowitnesses.
